Poly Butylene Adipate-Co-Terephthalate


Poly Butylene Adipate-Co-Terephthalate Instruction:

Poly Butylene Adipate-Co-Terephthalate is a thermoplastic biodegradable plastic, which is a copolymer of butylene adipate and butylene terephthalate. PBAT has the characteristics of both PBA and PBT, with good ductility and elongation at break, as well as good heat resistance and impact performance; in addition, PBAT also has excellent biodegradability, and is one of the most popular and best degradable materials in biodegradable plastic research and market application.

PBAT Characteristics:

PBAT is a semi-crystalline polymer, usually with a crystallization temperature around 110°C and a melting point around 130°C. The density of PBAT is between 1.18g/ml and 1.3g/ml. The crystallinity of PBAT is about 30% and the Shore hardness is above 85. PBAT is a copolymer of aliphatic and aromatic, combining the excellent degradation properties of aliphatic polyesters.

The processing performance of PBAT is very similar to that of LDPE and can be blown with LDPE processing equipment.PBAT, the Chinese name is polybutylene terephthalate-adipate. According to the source of biodegradable plastic, PBAT can be divided into bio-based biodegradable material and petrochemical-based biodegradable material.

PBAT belongs to petrochemical-based biodegradable plastic, which is one of the most active biodegradable materials in the research and market application of biodegradable plastic.
